Abstract (en)
[origin: EP0715277A2] A method and apparatus includes a geometry transfer engine (GTE) 61 acting as a coordinate transforming means for converting three-dimensional image data of TMD format into two-dimensional image data by perspective view transformation, and a graphics processing unit (GPU) 62 acting as a drawing means for transferring the two-dimensional image data in a given transmission standard to draw an image on a two-dimensional display screen. A structure of the three-dimensional image data, excluding the information to be perspective view transformed, is arranged identical to that of the given transmission standard of the two-dimensional image data. Accordingly, in the GTE 61, the information to be perspective view transformed is discriminated from the other data of the three-dimensional image data wherein the structure is identical to that of the given transmission standard of the two-dimensional image data, subjected to the perspective view transformation, and is combined with the other data wherein the structure is identical to that of the given transmission standard for production of the two-dimensional image data. An original format file including data to be transformed is thereby easily converted into a file having a new format. <IMAGE>
